AF P&S that focus as you half press the shutter?

It's a bit bigger than a P&S, but the Hexar AF does this as well. In P mode it works exactly like a P&S but with a fantastic F2 lens, great VF, and the option for manual control.
 
The focus locks on pretty much any 35mm point and shoot when the release is depressed half way and held. I think the OP was inquiring whether the lens actually physically moves when this is done, not that I understand what difference this makes on the final image.

There won't be any, if you shoot only things are absolutely still.

Some cameras really take their time extending their lenses into position. That's some extra waiting time for you after you released the shutter.

That makes sense. Thank you for explaining. Things rarely move fast enough around here for that to be much of an issue for me. ;)
 
Most AF P&S cameras will calculate focus when you half depress the shutter button, but when I was looking for one, many moved the lens into position after full depress even though half-depress had been done and focus ascertained. This doesn't make sense to me, but there must be a reason other than stupidity of designers. Even the Leica film P&S zoom that I owned for a week did it: the delay was huge. The Ricoh GR1v doesn't have such a delay, but it has a very common fault with the display, so I can't recommend it.

One benefit, though not intentional, would be it improves longevity of the printed circuit board wire that every AF retractable lens has inside.

They move and fold with the lens action and will eventually break. Some are more prone to this, for example the infamous E02 problem of the Minilux. Eliminating unnecessary movements (times you half press but didn't fire) reduces the risk.

That maybe why cameras like the Contax T3 has a customize function for it...
 
What you define as "focus". With half-press they all acquire focusing distance.
If you want compact which already moves lens into position to match focus, they are not so common to save physical resource as described by Archlich.

One compact I remember which moves lens at half-press is Fuji DL500, nice dual focus setup but unfortunately it died on me.
 
Leica Minilux (non-zoom). Focusses and already extends the lens when the shutter is pressed halfway. After that, full press gives immediate shutter release. Same goes for the Konica Hexar. Others already pointed out the 28/35Ti.

Come to think of it, those are all expensive compacts.. Could it be that the cheaper ones have a single motor that extends the lens and actuates the shutter in a single action?
